| Enable support for the Qualcomm Technologies HIDMA Management. |
| Each DMA device requires one management interface driver |
| for basic initialization before QCOM_HIDMA channel driver can |
| start managing the channels. In a virtualized environment, |
| the guest OS would run QCOM_HIDMA channel driver and the |
| host would run the QCOM_HIDMA_MGMT management driver. |

| Enable support for the Qualcomm Technologies HIDMA controller. |
| The HIDMA controller supports optimized buffer copies |
| (user to kernel, kernel to kernel, etc.). It only supports |
| memcpy interface. The core is not intended for general |
| purpose slave DMA. |
